Using Wire-To-Board PCB-Mounted Connectors in Your Cable Assembly
In easy phrases, cable assemblies are comprised of two major components: the conductor and the connector. Rightfully so, the conductor’s sole function is to pass present at a given voltage, whereas the connectors job is to affix the cable meeting securely to a mating interconnect. It’s clear that the conductor High-speed PCB connector and connector garner most of the designer’s focus when designing cable assemblies, but typically the particular details of the right way to attach the connector to the wire are neglected. For instance, forgetting to buy the suitable crimp and extraction tooling on your custom cable construct will delay your build, particularly if these are lengthy lead time or expensive tools. But what happens if three months into your program it’s decided that your specified connector was never meant to attach directly to a cable? What occurs if the wire-to-board connector required must now be used as a wire-to-wire connector? Most connectors have both a male or feminine gender. Connectors are also designed in wire-to-wire or wire-to-board methods to differentiate the application and installation necessities.
Wire-to-wire connector systems are self-explanatory. If you beloved this article and you also would like to be given more info pertaining to PCB header connector – Recommended Reading – please visit our webpage. The wires are affixed to the male and feminine sides of the connector utilizing both a soldered or a mechanical connection to a jacketed wire. Your family extension cord is an easy example of a wire-to-wire system. Example of a wire-to-wire cable meeting. A wire-to-board connector system consists of a male and feminine set of connectors, with one being terminated to a cable harness and the opposite aspect being hooked up to a High-density PCB connector (printed circuit board). Instead of utilizing a crimp terminal and housing system, sometimes the “board” aspect of a wire-to-board connector system makes use of pins which are soldered to by holes or surface mounted to pads on the PCB. This attachment methodology is extraordinarily common in SMT (surface-mount know-how) manufacturing. An on a regular basis instance of a wire-to-board join system is the USB receptacle in your laptop that mates together with your USB keyboard cable (identical to what I’m using at present!).

If you find yourself scrambling to employ a PCB-mounted connector directly in your cable assembly, there are options to consider that will prevent a major design change. Before exploring a number of the doable options on how to make use of a printed circuit board-mounted connector, it’s finest to investigate the applying and use case to fully perceive the mechanical, environmental, and electrical requirement impacts. Ruggedization: Will your cable meeting be exposed to mechanical shock, vibration, or cyclic bending? Is there an anticipated quantity of flexure that is required? Will the application have a pull strength requirement that may require strain relief? Knowing the qualification necessities or how the cable assembly will likely be used can present the necessary details to select the best attachment choice. Environmental: Some buyer purposes require resilience to certain chemicals or solvents, and others have ingress requirements like an IP66 waterproof ranking. If a corrosion concern exists as a result of exposure to salt fog or other forms of oxidation, this have to be considered before deciding on a design strategy.
Other issues akin to UV publicity, temperature cycling, and extended publicity to humidity can also dictate the solution employed to terminate your PCB connector to your wire harness. All these necessities can drive the design and manufacturing process utilized. Electrical: Low complexity headers and other surface mounted interconnect designs often haven’t any want for shielding. It’s possible the applying is passing low-voltage data, or the system is just not vulnerable to ESD (electrostatic discharge) or radiated emissions, decreasing the necessity for shielding. Understanding if there are shielding requirements is vital earlier than launching manufacturing. If the connector is intended to cross high-velocity information or other another excessive-fidelity sign, this have to be thought-about earlier than selecting a design strategy. Once it has been decided that there aren’t any other sensible options to swap to a wire-to-wire connector answer, there are strategies to use a printed circuit board-mounted connector directly in your cable meeting.
